umount -r
We have as a part of our shutdown scripts:
umount -a -d -r -t notmpfs,nosysfs,nodevtmpfs,noproc
What we expect is that the rootfs (/) will fail, but be remounted read only. This doesn't seem to be happening because we get messages about recovery needed during the next boot.
We can work around it by adding
mount -n -o remount,ro /
I have a report that umount works as expected in version 2.21.2, but not in 2.22.2 or later. I this a misunderstanding about umount or a bug?
